' ,gous grain and to carry on the scouring or cleaning operation of the grain without permitting the dust or dirt to mingle or remain fin association therewith.

A" further object of the invention is to {provide va grain scouring or cleaning machine having adjustable features to regulate the operation of the machine relatively to the grain or, to effect a light or heavy scouring action, and furthermore, to provide for. a scouring .action relatively to the grain by only apart jof the machine in accordance withthe' primaryjcondition of the grainor as effective cleaningof the grain-may require. I

With these and other objects and advantages in view theinvention :consists in the' construction andarrangemen't of the several parts which will be more fully hereinafter described and claimed.

By adjusting the blades or vanes 24: the air presthe bolts 27 the blades or vanes may be moved outwardly relatively to the blades or vanes 24 or inwardly from the latter to decrease or increase the air pressure relatively to the screen as just explained.

As shown, the grain is admitted to the machine through a suitable feed pipe 28 which is located adjacent to the end of the shaft 16 having the pulley l7 thereon, the said pipe 28 connecting with an inlet chute 29 which opens into a feed box 30, shown in detail by Fig. 5. The feed box 30 has at its inner wall suitable guides or seats 31, and cooperating therewith is a slide 32, an opening being formed through the foraminous cylinder or screen l8 at this point and the slide also having an opening 34 therein. illhrr'siide 32 has a handle projecting through one extremity ofthefeed box exteriorly of the machine so that it may be readily adjusted, and an angular clip 36 is secured on the lower portion of the slide and engages the lower guide or seat 31 of the feed box, the upper edge of the said slide engaging the upper guide or seat 31 of said box. i'e slide 32 is also supported in its operative position bya lower strip 37 and an upper strip 38 which may be a part of the feed box. The slide cooperates with the channels 39, 40 and all between the one side of the casing and the ribs 20, 20 and 20 the opening 83 being of such dimensions as to take in these channels or compartments between the ribs just specified and the slide may be adjusted to deliver the grain into either one of t-hesechannels when the grain may only require a partial operation of the machine thereon. By adjusting the slide 32 inwardly and outwardly the opening 34 is brought into registration with the different channelsor compartments'39, l0 and 41 and the grain from the box '30 is thus directed into any one of the channels. 7

The slide 32, as will be understood, forms the inner wall of the feed box 30 and the opening 33 through the fo'raminous cylinder or screen' extends in the direction of the feed box to. facilitate the inflowing or the grain. It will be seen that the. grain when admitted to the first channel-41* will be caused to pass through the entire series of channels by the action Oil the spiral ribs 20 20", etc., which will tend to feed the grain transversely of the machine and in close contact with the foraminous cylinder or screen 18 so as to' cause grain to thoroughly wash the latter in a thin sheet and the dust and dirt are thereby driven outwardly therefrom through the cylinder'or screen 18 into the compartment 19, the grain being turned over as it is caused to move from one side of the machine to the opposite side thereof. i

At the side of the machine opposite that having the/inlet for the grain, an outlet chute or spout 42 is disposed and communicates with the last channel or compartment of the series of channels between the spiral of an elbow, as shown by Fig. 7, and communicating with an outlet spout or' duct 43 whichimay extend cit from the machineany suitable distance at an angle, as shown by Fig. 3; r

To render the casing of the machine accessible at different points, a hand-hole 44 is. formed in one side and normally closed 2 by a slide 45, and at the lower part of the sheathing is a similar hand-hole 46 which is normally closed by a slide 47. The slides 45 and 47 may be readily opened at any time desired to permit the operator to insert the. 5 hand in the machine to regulate or adjust 1 0 the blades or vanes 25 and to reach the slide or for other purposes.

In theoperation of the machine the grain is fed into the box 30 through. the pipe 28 and inlet duct or chute 29 and admitted into 05 the channels between the ribs 20, 20 20, etc., or to either one of the latter, and is thrown out against the inner side of the foraminous cylinder or screen. 18 and spread in a thin layer and held in such position by the fan blades 24 and the air forced thereagainst the air, being blown through the 7 grain and carrying the dust, dirt or smut outwardly through the foramlnous cylinder or screen 18 into the chamber l9,the dust,

dust and dirt from the grain in accordance with the primary condition of the latter, and, furthermore, the parts of the machine are comparatively simple and may be easily 1 reached for adjustment and repair.

The intensity of theair current may be 85 ribs, the chute or outlet 42 being in the torm Varied by speeding the machine either high or low and the grain is not broken or inured as 1t has light or limited contact with the fan blades owing to the action of the air driving the grain outwardly against the foraminous cylinder or screen. Furthermore, the grain will be maintained in the individual channels and will'not be permitted to jump from one channel to another, and all tudinally unobstructed spiral grain chanof the grain will therefore be subjected to the same relative cleaning period and action, with material advantages in effectively removing the dirt and dust from the grain. What is claimed is: 1. In a grain scourer or'cleaner of the class specified, the combination of a casing,
